I was looking up things that are made out of ferrite other than ferrite cores, and I noticed that VHS tape among other things is coated with ferrite powder. If I wrapped a cord with the tape from a VHS/audiocassette would it have any positive effect? Asking this because I have plenty of old videocassettes I have no use for/ could get more for practically nothing if I search yard sales for tapes nobody ever wants (how to use your Nordictrack etc.), and I have plenty of things like that at home as it is

good thinking
It's a really thin coating and if you wrap a lot of turns is stll just a fraction to a percent of the total. I'm sure it would have a positive effect at higher freqs but not enough to claim victory over tried and true ferrite cores. Go for it

in case you were wondering it did have an effect, obviously just one layer of it doesn't do much but the whole reel definitely makes a difference. I think it at least works better than the Radioshack stuff which is as far as I've messed with it up to this point

audio systems cannot be treated with kortizone ..... kortizone is a medichine that will supress the problem ...push it down and if the pation is healty in between it might be shelf fixed and or with the combination of other medichine ...

the best treatmend should be to find what causes the trouble and fix it not to supress it ...
